Textbox with multiple rows allows to input more symbols when define in textbox property 'maxlength'

Please see example: http://zkfiddle.org/sample/1p6rrrj/2-Another-new-ZK-fiddle
Try to copy into textbox text with more than in 'maxlength' defined symbols trough popup menu by right click (!!!) and choosing Paste. Typing and using Ctrl+V combination works fine. Also all works fine with textbox with single row.
